Duke Ellington called him "the world's greatest drummer," and Bellson, to this day, lives up to the description. He's a composer, arranger, bandleader, tireless jazz educator, pioneered the use of two bass drums, and in terms of the speed of his hands and feet and the wonderful, percussive "ideas" he conveys on the drums, stands next to only Buddy Rich as the total technician.
